BRAKE-OPERATING MECHANISM.

Specification of Letters Patent.

Application filed April 7, 1910.

Patented Aug. 30, 1910.

Serial No. 554,049.

To all whom it may concern:

Be it known that I, JACOB F. Kmrrnn, a citizen of the United States,residing at Plimpton, in the county of Holmes and State of Ohio, haveinvented certain new and useful Improvements in Brake OperatingMechanism; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to mechanism for working the wheel brake of awagon when used in connection with a hay-rack; and it consists in thenovel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure 1 is a side view of portions of a wagon providedwith brake operating mechanism according to this in vention, and showingthe frame raised. Fig. is a front view of the mechanism, drawn to alarger scale. Fig. 3 is a side view of the mechanism showing it foldeddown.

A is a wagon of any approved construction; and B is a hayrack of anyapproved construct-ion which is mounted on the wagon.

C is a wheel brake of any approved construction applied to the wagon andc is the pivoted lever which works the brake. hen a load of hay isplaced on the rack it is desirable to be able to work the brake from thetop of the load and at its front end, and the novel mechanism isprovided for that purose. p D is a frame formed of suitable uprights andcross-pieces, and having a strong crossbar (Z at its bottom. Thiscrossbar (Z is provided with pivot pins d which engage with holes in thefront end portions of the side pieces 6 of the hay-rack.

E is a bracket secured to the top end portion of the frame D; and F is aguide secured to the middle portion of the said frame.

G is a guide-bar which is rectangular in cross-section, and which isslidable in the guide F. A screw 9 projects from the top end of theguidebar G, and is slidable'in a hole in the bracket'E. H is a handlepro vided with a nut 72. which engages with the upper end portion of thescrew 9 above the bracket E. The screw is preferably provided with adouble screw thread to make it quick acting.

I is a flexible connection secured to the lower end of the guide-bar Gand operatively connected with the brake-lever o. This flexibleconnection may be a cord, chain, wire or any other similar device.

J is a guide sheave journaled on a pin which is carried by the lowerpart of the frame D.

K is a guide sheave journaled on a pin is, and arranged in a slot in inone of the side pieces 6 of the hay-rack.

The flexible connection I passes over the guide sheaves J and K, and thesaid guide sheaves are arranged with respect to each other and the pivotpins of the frame, so that the brake can be operated when the frame isin a vertical position, as shown in Fig. 1, and bearing against astop-bar m on the hay-rack, and also when the frame is turned downward,as shown in Fig. 3.

The frame is arranged vertically when a load of hay is on the rack, andthe man on top of the load can then work the brake with facility. Whenno load is on the rack, the frame is turned downward, as shown in Fig.3, so that it rests against one of the crosspieces b of the rack, andthe brake can then be operated with the same facility.

Under ordinary circumstances the brake is applied by revolving thehandle H, but when the brake requires to be applied suddenly, in anemergency, the handle H is seized and is pulled upon to slide the screwlongitudinally in the guide without revolving the handle.

WVhat I claim is:

1. The combination, with a wheeled vehicle provided with a wheel brake,of an upright pivoted to the vehicle frame, a bracket secured to thefree end portion of the upright, a screw slidable longitudinally in thesaid bracket, means for preventing the said screw from revolving,connections between the said screw and wheel brake, and revoluble handleprovided with a screwthreaded portion which engages with the projectingend portion of the said screw above the said bracket and which is slidlongitudinally with the screw to apply the guide secured to the uprightbelow the said longitudinally with the screw to apply the 10 bracket, ascrew slidable in the said bracket brake quickly in an emergency.

,and provided with a rectangular bar which In testimony whereof I haveaflixed my slides in the said guide and prevents the screw signature inthe presence of two witnesses. from revolvin means for operativelyconnecting the sa id bar with the wheel-brake, JACOB KIEFFER' and arevoluble handle which engages with WVitnesses:

the projecting end portion of the said screw LEWIsA. LONG,

above the said bracket and which is slid I G. F. KANTZER.
